What is the value of y when x=7?

Mathematics

Gwar [14]3 years ago

The value of y would be 60

The way you would solve this is by plugging in 7 for x.
After you plug in the 7 for x you would have to multiply 7 by 4 to get 28.
Next you would add 28 to 32 to get 60.
Your final answer should be y=60

Y = 4x + 32                                       1. write the equation
y = 4(7) + 32                                     2. plug in missing numbers
y = 28 + 32                                       3. multiply 4 and 7
y = 60                                               4. add 28 and 32 to get final answer

Which of the following shows one way to simplify 43Σn=1(3+9n)?
kramer

Based on the given summation notation, the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

<h3>How to determine the summation expression?</h3>

The expression is given as:

43Σn=1(3+9n)

As a general rule, if a summation notation is represented using the following expression

Σ(a + bn)

The equivalent expression of the above summation notation is

Σa + bn

Where the variable a is a constant in the expression

This means that:

Σ(a + bn) = Σa + bn

Using the above equation as a guide, we have the following equivalent equation

43 Σ n=1 (3+9n) = 43 Σ n=1 3 + 43 Σ n=1 9n

Hence, based on the given summation notation; the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

-10.9p + 3.9 = -9.18
Debora [2.8K]

Steps to solve:

-10.9p + 3.9 = -9.18

~Subtract 3.9 to both sides

-10.9p =  -13.08

~Divide -10/9 to both sides

p = 13.08/10.9

p = 1 1/5

Best of Luck!

The sides of the base of this square right prism are 16 centimeters each and the height of the prism is 10 centimeters. What is
Montano1993 [528]

The width (W) of the prism is 16 cm.

The length (L) of the prism is 16 cm.

The height (H) of the prism is 10 cm.

The formula for the surface area of any right prism with width W, length L, and height H is the following:

A = 2 (WL + LH + WH)

Substituting using our given values changes the equation to:

A = 2 (16*16 + 16*10 + 16*10)

= 2 (256 + 160 + 160) = 2 (576)

= 1152

Thus, the surface area is 1152 cm².

Let me know if you need any clarifications, thanks!
